NAME AtteanX::Store::SPARQL - Attean SPARQL store SYNOPSIS my $store = Attean->get_store('SPARQL')->new(endpoint_url => $url); DESCRIPTION This implements a simple immutable triple store, which simply allows programmers to use Attean facilities to query remote SPARQL endpoints. This distribution also brings a corresponding AtteanX::Model::SPARQL, which allows query plans to be made, and a AtteanX::Plan::SPARQLBGP plan class, which contains a rudimentary cost estimate that attempts to avoid sending Cartesian joins to remote endpoints if possible. Attributes and methods `endpoint_url` The URL of a remote SPARQL endpoint. Will be coerced into a URI object, so it may be set as a string or whatever. Required attribute. `ua` An LWP::UserAgent object to use for remote queries. Will be set to a reasonable default if not supplied. `get_triples` Method to query the remote endpoint, as required by Attean::API::TripleStore. `count_triples` Reimplemented using an aggregate query for greater efficiency. `get_sparql($sparql, [ $ua ])` Will submit the given $sparql query to the above `endpoint_url` attribute. Optionally, you may pass an LWP::UserAgent, if not it will use the user agent set using the `ua` method. Will return an iterator with the results if the request is successful.
